Free To Play Nature two deck archetypes.

As per the prompting, it will be an attempt to build the two Nature deck types. Nature is not my best deck, but this is what is useful for my Gauntlet runs. For non F2P players, these decks can be easily improved by adding better cards.

Both decks contain the standard Marsh Walker X2, Canopy Barrage X2, Faeflame Blade X2, Lightning Strike X2, Nefarious Briar X2, Giant Pangolin X2 cards. And both decks use Selena's Mark against Ludia or Auros. Finnian Fruitbearer is missing from these decks.

The Wide Deck is meant to field out many small creatures fast. Animal Bond; Wildfire X2, Bladefly X2 are the core cards for this deck. In an attempt to go faster, the experimental cards are Crescent Werewolf and Dogs Unchained. Keep an eye out for frenzied mechanics of Feral Cat, Moonlight Charm, Rabid Bear and Sudden Bloom. This deck is too fast for The Hunt, so use Firewine X2 for board control. As a last hope, the Tainted Treant can win the game. Feel free to add in a Vicious Manticore instead of the Valewarden Minotaur, Celestial Stag instead of the Tainted Treant, Starving Sabertooth instead of the Rabid Bear or buy a Falling Star instead of the second Firewine.

The Tall Deck is meant to field large creatures with more control. Flourish; Black Jaguar X2, Overgrown Rhino X2, Brazen Moose X2, are the main cards for this deck. Larger creatures warrant adding in Arrow of Rage X2. Frenzy cards are Blood and Bone X2, Feral Cat, Moonlight Charm, Rabid Bear X2, Sudden Bloom. You can buy a Jaguar Staff and put it instead of the second Hunt, maybe add in a Charging Oryx.

These two decks aren't mythic, but are alright for win farming at lower ranks.
